Point 5, clause 1 of the seasonal rules states:
5.1. The so-called "red rush" is prohibited, meaning a player playing as red does not have the right to attack on the first day of the week with growth purchased that day:
б) heroes or guarded mines of blue, if the presence of growth could affect the outcome of the battle or losses in the battle for any of the players.

IMO attacking a scout hero is not a serious reason for a tech loss, because the presence of growth could not affect the outcome of the game. Theoretically, there's no difference whether you chased off an enemy scout hero with 7 griffins from week 1 growth or with the full growth of 4 weeks. :) And purely from a human standpoint, there was no need to issue a tech loss to an opponent over something like that. But that's left to everyone's conscience... :) ;) :)

I didn't just have a single unit there. There were about 30 stone golems, close to 60 archers, and a few gargoyles. He was standing at a stable, which was fine for tempo, especially since this hero wasn't redundant, positioned at the intersection of our main roads. That's point one. Secondly, how do you figure it doesn't affect anything? This game has many small details, and generally, it's not for you to judge; in some situations, if I mess up—I personally ask the organizers to count it as a loss for any violation. Thirdly, sometimes 1 MP plays a role, and you're talking about such supposed insignificance! Let's now always ask the admin if we're 1 movement point short of an external dwelling of angels or dragons! And because of that undrawn dwelling, the entire game might slip away! A game that can last several days! In this game, there are no small details! How many games have been won where after Armageddon, 3 golems remained in the fireball, where difficult fights were pulled off with minimal units, where luck and pure fortune led to victory! And don't tell me about what should or shouldn't be done—act as you see fit in your own place, and I myself have asked the organizers to count a won game as a loss later, because out of stupidity and inattention, I passed through to someone else's respawn past a disguised guard.
